夾心粉圓螢石-福建
Fluorite secondary recrystallization - Fujian
螢石(Fluorite或Fluorspar或Fluor),又稱氟石、砩石,是一種礦物,其主要成分是氟化鈣(CaF2),含雜質較多。其中的鈣常被釔和鈰等稀土元素替代,此外還含有少量的Fe2O3、SiO2和微量的Cl、O3和He等。自然界中的螢石常顯
鮮艷的顏色,硬度比小刀低。它的色散極低,對紅外線、紫外線的透過性能高,適合做光學元件。
這個特別的螢石,像極了台灣有名甜點珍珠粉圓,在紫芯外層包裹著透明的螢石,就像糖果似的,目前在市面上也佷難得一見
Fluorite (Fluorite or Fluorspar or Fluor), also known as fluorite or fluorite, is a mineral with calcium fluoride (CaF2) as the main component and containing a variety of impurities. Among them, calcium is often replaced by rare earth elements such as yttrium and cerium. In addition, it also contains a small amount of Fe2O3, SiO2 and trace amounts of Cl, O3 and He. Fluorite in nature tends to show bright colors, and its hardness is lower than that of a knife. It has extremely low dispersion and high transmittance to infrared and ultraviolet, making it suitable for optical components.
This special fluorite is very similar to the famous Taiwanese dessert tapioca. Transparent fluorite is wrapped in the outer layer of the purple nucleus. It is like a candy. It is also rare on the market.
